Challenge and Wins


Navigating Constraints

The customer had deployed many stored procedures in Netezza which required work to be migrated, thus they wanted to avoid creating any native stored procedures to their future platform. Snowflake also was not ready to have their private preview of stored procedures used for such a complex production scenario. This introduced a major roadblock as the stored procedures were highly elaborate, and depended heavily on nested procedures. Additionally, the people that wrote the stored procedures were no longer employed by the customer. Thus, Intricity had to reverse engineer all the code which contained all the business logic. The customer also had many shell scripts that called the Netezza Stored Procedures. Every step in the stored procedures was logged in the Netezza deployment, and this level of logging was something that the customer insisted be kept in the future Snowflake deployment. This was because the people who wrote the stored procedures no longer worked for the customer. However, they could read the results of the logs and determine what to fix.
